Wii Balance Board first appears in the game when the player first starts the game. He will introduce the player to the game.

Later on, he will sort of serve as just a prop that appears in the background at some points. However he will appear whenever a player loads his/her file and just welcome back the player. He also appears when a player does his/her daily body test. Hisrole is very large here.

He doesn't talk much, but sometimes will shout quotes depending on what the player does, such as "Good Evening". Whatever he's trying to say will appear in a big box beside him.

If you play the game on your birthday, he will be wearing a birthday hat and give you a special birthday message when you sign in (Complete with knowing your age!). Though if you do not play the game for a long time, the Wii Balance Board will forget and confuse your name with other Miis in your Wii Fit Plaza.
